  Log:
  Introduce the KDB debugger frontend. The frontend provides a framework
  in which multiple (presumably different) debugger backends can be
  configured and which provides basic services to those backends.
  Besides providing services to backends, it also serves as the single
  point of contact for any and all code that wants to make use of the
  debugger functions, such as entering the debugger or handling of the
  alternate break sequence. For this purpose, the frontend has been
  made non-optional.
  All debugger requests are forwarded or handed over to the current
  backend, if applicable. Selection of the current backend is done by
  the debug.kdb.current sysctl. A list of configured backends can be
  obtained with the debug.kdb.available sysctl. One can enter the
  debugger by writing to the debug.kdb.enter sysctl.
